Read the CurseForge ZIP
The ZIP is opened locally in the browser and manifest.json is validated before conversion continues.

What the ZIP to MRPack converter reads
Use this page for CurseForge ZIP exports that include manifest.json plus the optional overrides directory.
The converter reads project and file references from manifest.json, keeps override files as bundled content, and prepares a Modrinth-compatible .mrpack output.
How the conversion works
The browser reads the archive, resolves CurseForge metadata, performs Modrinth matching, and then builds the MRPack.
Resolve and match files
CurseForge file metadata is requested through the protected API proxy, then compatible files are checked with Modrinth matching.
Build the MRPack
Matched files become Modrinth references, while CurseForge-only files and overrides are bundled into the output.
Limits and failure cases
These limits describe what the converter can prove safely in the browser and where conversion can stop.
CurseForge export shape
The ZIP must contain a readable manifest.json. Missing or malformed manifests are failure cases because there is no reliable file list to convert.
Protected metadata lookup
CurseForge file metadata goes through a protected API proxy. If that proxy or the CurseForge response fails, matching and bundling can be incomplete.
Privacy boundary
The archive is read in the browser. The privacy boundary is that file metadata may be sent to the proxy for lookup, while the local ZIP itself is not uploaded as a whole conversion job.
